I thought that the Rubi's had SYE from the factory. If so then I wouldn't see why you would need it. Have you checked one of the rubi forums to see what those guys are doing?
I would say put the lift on...drive it and see if there are any vibs. If there arent any vibs it should be fine...if there are put the drop in, I dont think they are that hard and don't take very much time.
well from what I understand I needed the rear upper arms to correct the pinon angle...so if that does the trick I shouldnt need the t case drop..Ill tell them to leave it off first
3" full traction lift
since I purchased the rear upper arms will I need to do the t-case drop when I get the rubicon lifted?
If I dont need the drop then Im definitely gonna be happy about all the extra clearence
No transfer case drop needed. on the 97-03s you would drop the t-case but on the 04-06s you utilize adjustable cams on the rear upper or new adj. uppers like the ones you purchased. IIRC
My friend's rub unlimited has more lift, but he put t-case lowering kit and 1" motor lift. I don't personally know, but that's what kept his drive line in correct angles.
